The present invention refers t o improve merits in machines forsharpening wooden toothpicks and other similar articlesyby the use ofwhich it is possible to obtain a greater perfection and finish andprincipally a maximum and notable" production, thereby re- H g i theshaft 'e' by mean's of; pul l eysle' o ducing labour and cost.

The inventlon is carried out "as hereinafterdescnbed, reference'beinghad to the 0 accompanying drawings, wherein:
